Questions

Is there a KiCad symbol and footprint for the ISO7840FDW?

Yes. The symbol is EasyEDA_Cloud:ISO6440FDWRQ1 and the footprint Package_SO:SOIC-16W_7.5x10.3mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the ISO7840FDW?

SOIC-16-300mil, with 16 pins. Its footprint is drawn on this page.

Where is the ISO7840FDW datasheet?

Texas Instruments publishes it: the Datasheet link on this page opens it.

Where can I order the ISO7840FDW?

JLCPCB lists it as part C2860645, with 0 in stock; the sellers' links on this page open their listings.

What can replace the ISO7840FDW?

Parts like it in the library: the ISO7741DW by Texas Instruments, the SSP5840ED by Shanghai Siproin Microelectronics, the ISO7740DW by Texas Instruments and the ISO7760FDWR by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
